Webb25 feb. 2024 · A hash table is essentially a pre-computed database of hashes. Dictionaries and random strings are run through a selected hash function and the input/hash mapping is stored in a table. The attacker can then simply do a password reverse lookup by using the hashes from a stolen password database. WebbStoring the salt unencrypted in the database next to the hashed passwords is not a problem. The purpose of the salt is not to be secret. It's purpose is to be different for each hash (i.e. random), and long enough to defeat the use of rainbow tables when an attacker gets his hands on the database.
